Introduction & Overview TACMET II, RLST Weather Station

Overview
Met One’s TACMET II, RLST Weather system (P/N 102352) is a rugged, stand-alone weather station to provides accurate measurements of wind speed, wind direction, temperature, relative humidity, and barometric pressure. An internal flux-gate compass automatically orients the wind direction to magnetic north. The TACMET II, RLST has no moving parts and is ideally suited for use wherever rugged, reliable, maintenance-free operation over a wide operating range under adverse operating conditions is required. The TACMET II, RLST is painted CARC Green 383 per military specifications.

Installation

• Be sure to mount the sensor in a clear, open area to minimize any turbulent effects caused by local obstructions (e.g., trees, buildings, etc.). The sensor mounts on the prewired sensor mount, P/N 102287. The connector key is matched to the keyway on its mate and secured by turning the connector’s collar until tight.
• If using the 102621 Quick Mount, attach the sensor to the mount by inserting the sensor into the top of the mount, attaching the latch springs to the clips on the bottom of the sensor, and snapping them down to lock the sensor in place.
• It may be necessary to rotate the sensor 180° to allow the keyway to seat properly.
• On the 102621 mounts, loosen the thumb screws in the bottom of the mount that attach it to your vertical ¾ inch pipe, rotate the sensor to the North, then retighten the thumb screws. The connector keyways assure correct alignment if the sensor is removed and re-installed at any time.

Input/Output Connections

The sensors’ pin designations are as follows:
PIN FUNCTION

• A Power Ground
• B 9.0 – 36.0 Vdc
• C N/C
• D N/C

User Interface

• The output of the TACMET II, RLST is a serial data stream at 19.2k baud (N/8/1). An example of the output format is shown below: 01+D008. 02+006.8 03+063.2 04+075.2 05+015.1 06+30.26
• The first parameter is the ID number of the sensor (D008), the second parameter is the wind speed (in mph), the third parameter is the wind direction(in°), the fourth parameter is the temperature (in° F), the fifth parameter is the relative humidity (in %) and the sixth parameter is the barometric pressure (in Hg). All parameters have fixed decimal points with leading zeroes.

Note: With the flux gate compass in the sensor package, the wind direction output is oriented relative to the magnetic north.

Calibration

• The sensor requires a wind tunnel for calibration.
• Recommended calibration is once every two years.
• Please contact Service for pricing.

Maintenance

• Because the sensor has no moving parts to wear out, the sensor does not require periodic maintenance.
• In extremely corrosive environments, the condition of the connector used to mount the sensor should be checked.
• In harsh environments, the transducer screens should be checked for dust/sand buildup.
• To clean the transducer screens, hold the unit upright and brush the transducer screens with an acid brush.
• There are no adjustments or user-repairable parts located inside the sensor.

Appendix B Theory of Operation

Winds
Met One’s sonic anemometer operates on the principle that the speed of the wind affects the time it takes for sound to travel from one point to a second point. If the sound is traveling in the direction of the wind then the transit time is decreased. If the sound is traveling in a direction opposite the wind then the transit time is increased. This principle is well known and is the basis of most sonic anemometers.

Temperature/Humidity
The temperature sensor in the P/N 102352 TACMET II uses a precision single-element thermistor. This provides a highly accurate and stable temperature reading. The resistance value is 10K ohms at 25°C. The TACMET II interfaces directly with the temperature sensor without additional electronics; sensor compensation is handled through software.
The relative humidity sensor is a capacitive element sensor. It has a linear voltage output, which is connected directly to the TACMET II microprocessor. The humidity sensor element’s construction provides excellent resistance to wetting, dust, dirt, oils, and common environmental chemicals. A heavy contaminant layer of dirt will slow down the sensor’s response time because it will take longer for water vapor to equilibrate in the sensor.

Barometric Pressure
The P/N 102555 barometer uses proven silicon sensor technology with microprocessor-based signal compensation, eliminating the need to insulate or temperature-regulate the barometer. The P/N 102555 has a pressure range of 500 to 1200 hPa. The P/N 102555 has a TTL output that lowers the power consumption of the barometer to 33 mW. The accuracy of the sensor is ±0.4 hPa (0.01 inHg).

Fluxgate Compass
The internal fluxgate compass is low power and compact and is a complete compass or magnetic sensor module that integrates easily into the TACMET II. The internal fluxgate compass uses two magneto-inductive sensors, which change inductance with different applied magnetic field strengths, to sense magnetic fields.
The TACMET II microprocessor measures the output of the internal fluxgate compass and then corrects the wind direction data for the orientation of the sensor. The output of the TACMET II wind direction is relative to magnetic North when a compass module has been specified.
